Barnes has the best physical tools out there. Big strong, can do everything. But physical game...I don't know.
Probably the most gifted at rolling a bowling ball is PDW. PDW's base ability is so incredible, if he could have gotten his head straight, in my opinion we wouldn't be talking about WRW having passed Earl Anthony, we would be talking about PDW.
Duke is a magician. Without the raw physical tools, he makes the ball do what he wants.
But for sheer head into the game, WRW. Roll ball over target. Repeat as needed.
